The topical anesthetic formulation of the present invention is typically a
solution that preferably includes lidocaine, USP as the active anesthetic
ingredient with benzyl alcohol and isopropyl alcohol. This invention
deals with problems commonly associated with topical application of local
anesthetics such as: slow onset of action; need for occlusion; messiness
of creams, ointments or gels; and rapid loss of effect due to rapid
systemic dispersion. The invention permits enhanced penetration of the
anesthetic and thereby allows for a lesser total dosage of
pharmaceutically active ingredient. The use of a lesser total dosage also
decreases systemic toxicity.
